Brief history of the summer school, and motivation
The summer school was started by Shravan Vasishth in 2017, as part of a methods project funded within the SFB 1287. The summer school aims to fill a gap in statistics education, specifically within the fields of linguistics and psychology. One goal of the summer school is to provide comprehensive training in the theory and application of statistics, with a special focus on the linear mixed model. Another major goal is to make Bayesian data analysis a standard part of the toolkit for the linguistics and psychology researcher. Over time, the summer school has evolved to have at least four parallel streams: foundational and advanced courses in frequentist and Bayesian statistics. These may be expanded to more parallel sessions in future editions. We typically admit a total of 120 participants (in 2019, we had some 450 applications). In addition to the all-day courses, we regularly invite speakers to give lectures on important current issues relating to statistics. Previous editions of the summer school: 2023, 2022, 2021, 2020, 2019, 2018, 2017.Code of conduct
All participants will be expected to follow the (code of conduct, taken from StanCon 2018. In case a participant has any concerns, please contact any of the following instructors: Audrey Bürki, Anna Laurinavichyute, Shravan Vasishth, Bruno Nicenboim, or Reinhold Kliegl.Keynote speakers

Title: A United Discipline: Hierarchical Modeling of Individual Differences in Cognitive Experiments
In his 1957 presidential address to the American Psychological Association, Lee Cronbach famously described psychology as two distinct disciplines: One concerned primarily with the experimental method and one concerned primarily with the correlational method. Cronbach proposed that these two disciplines be merged, promising more coherent theory, methodology, and practical recommendations. In my talk, I will review efforts at "Cronbach's merger" over the past 25 years in the field of attentional control, where researchers attempt to study individual differences using experiments. I will discuss issues of the merger from both the correlational and experimental sides, focusing on the reliability and validity of attentional control experiments. Throughout, I will highlight how hierarchical modeling as a statistical tool and cognitive modeling as a theoretical tool may (or may not) help to address some of these issues.

Courses
You can decide whether this course is appropriate for you by looking at the online version of this course (videos are available): see here.
This course is an introduction to Bayesian modeling, oriented towards linguists and psychologists. Topics to be covered: Introduction to Bayesian data analysis, Linear Modeling, Hierarchical Models. We will cover these topics within the context of an applied Bayesian workflow that includes exploratory data analysis, model fitting, and model checking using simulation.
Prerequisites: Participants are expected to be familiar with frequentist methodology (what is taught in the foundations course, see below, as well as this online textbook: here), be relatively fluent in R usage, and must have some experience in data analysis, particularly with the R library lme4. Basic high school (pre-calculus) arithmetic and mathematical fluency is assumed; for example, you should know what a log is, what an exponent is, and be able to solve for y in x=log(y/(1-y)). If you are unfamiliar with frequentist methods, we suggest taking the introductory frequentist course listed below.
Course Materials Textbook: here. We will work through the first six chapters, plus the chapter on Bayes factors.
This course assumes that participants have some experience in Bayesian modeling already using brms and want to transition to Stan to learn more advanced methods and start building simple computational cognitive models. Participants should have worked through or be familiar with the material in the first five chapters of our book draft: Introduction to Bayesian Data Analysis for Cognitive Science. In this course, we will cover Parts III to V of our book draft: model comparison using Bayes factors and k-fold cross validation, introduction and relatively advanced models with Stan, and simple computational cognitive models.
Course Materials Textbook here. We will start from Part III of the book (Advanced models with Stan). Participants are expected to be familiar with the first five chapters.
Participants will be expected to have used linear mixed models before, to the level of the textbook by Winter (2019, Statistics for Linguists), and want to acquire a deeper knowledge of frequentist foundations, and understand the linear mixed modeling framework more deeply. Participants are also expected to have fit multiple regressions. We will cover model selection, contrast coding, with a heavy emphasis on simulations to compute power and to understand what the model implies. We will work on (at least some of) the participants' own datasets. This course is not appropriate for researchers new to R or to frequentist statistics.

Applicants must have experience with linear mixed models and be interested in learning how to carry out such analyses with the Julia-based MixedModels.jl package) (i.e., the analogue of the R-based lme4 package). MixedModels.jl has some significant advantages stemming from a faster implementation incorporating several algorithmic advances. The speed improvements make it easier to fit larger and more complex models as well as perform the repetitive model fitting necessary for power simulation and bootstrapping.
We do not expect profound knowledge of Julia from participants; the necessary subset of knowledge will be taught on the first day of the course. We do expect a readiness to install Julia and the confidence that with some basic instruction participants will be able to adapt prepared Julia scripts for their own data or to adapt some of their own lme4-commands to the equivalent MixedModels.jl-commands. There is good interoperability between R and Julia (with RCall on the Julia side and JuliaCall on the R side) so that users can continue using R as necessary for e.g. data wrangling and plotting.
